UPDATE: 9:25 a.m. EDT -- The university issued an "all clear" Wednesday about 20 minutes after starting up emergency sirens while police investigated unconfirmed reports of an armed person near the NROTC Building and Venable Hall, which houses chemistry and marine science classrooms.
"The all-clear signal means the threat to the campus is over," it wrote on its Alert Carolina website, adding that students and staff should resume normal activities.
UNC Chapel Hill, located in Chapel Hill, North Carolina, has about 29,000 students. This year, three Muslim students were fatally shot at a nearby apartment complex by their neighbor over an alleged parking dispute. Craig Stephen Hicks was charged in the deaths of Deah Barakat, Yusor Abu-Salha and Razan Abu-Salh in what some have called a hate crime.
